ios - Swift 3: Update table View after deleting the data from Core Data -

i trying remove , update data on table view. when mark profile "not favourite", deletes core database, however, still not removes table view. have 1 view controller ( profile view controller add favorite table) , other 1 table view controller ( favorite view controller). when click on 1st view controller add fav, saves record. when go second view controller see favs, can see list. now, remove 1 profile , mark not fav. able delete core database, but, table not reload. when restart app. see 1 marked not fav, removed still holds place on table view. when click on it, crashed down.

the code have:-

@ibaction func savefav(_ sender: uibutton) {     let propertytocheck = sender.currenttitle!     var proid = saved_id     let context = (uiapplication.shared.delegate as! appdelegate).persistentcontainer.viewcontext     let task = favprofile(context: context)      switch propertytocheck {     case "add favourite":      // link task & context     task.busname = bussinessname     task.profileid = int32(id!)!     print ("saved id is: - \(task.profileid)")     print ("saved profile name is: - \(task.busname)")     fav_remove_fav_button_label.settitle("remove favourite", for: .normal)      // save data coredata     (uiapplication.shared.delegate as! appdelegate).savecontext()      let _ = navigationcontroller?.popviewcontroller(animated: true)      let alert = uialertcontroller(title: "alert", message: "added favourite list", preferredstyle: uialertcontrollerstyle.alert)     alert.addaction(uialertaction(title: "ok", style: uialertactionstyle.default, handler: nil))     self.present(alert, animated: true, completion: nil)          case "remove favourite":                let fetchrequest = nsfetchrequest<nsfetchrequestresult>(entityname: "favprofile")             let predicate = nspredicate(format: "profileid == %@", id as! cvararg)             fetchrequest.predicate = predicate             let moc = getcontext()             let result = try? moc.fetch(fetchrequest)             let resultdata = result as! [favprofile]               object in resultdata {                 moc.delete(object)             }              {                 try moc.save()                 print("saved!")               //  notificationcenter.default.post(name: nsnotification.name(rawvalue: "load"), object: nil)                 let _ = navigationcontroller?.popviewcontroller(animated: true)             } catch let error nserror  {                 print("could not save \(error), \(error.userinfo)")             }                           let alert = uialertcontroller(title: "alert", message: "removed favourite list", preferredstyle: uialertcontrollerstyle.alert)         alert.addaction(uialertaction(title: "ok", style: uialertactionstyle.default, handler: nil))         self.present(alert, animated: true, completion: nil)       //  self.favtable.tableview.reloaddata()       default: break     } }
